Capacitors aren't so useful? how about capacitors with resistency?

Bronze Member Username: PanamanianPanama cityPanama Post Number: 45 Registered: Aug-05 | A low/mid amp alternator cannot supply too much power if you have a powerful equipment, bringing with that too many spikes and lows... right? if you use a capacitor you will smooth a little bit the spikes... if you combine a capacitor and a resistency (according to one site) your current will be sooooo smooth. how true is that? |

It will not fix dimming lights or other voltage problems. The resistance you are refering to is called "ESR". It is a measurement of the capacitor's internal resistance. This is the most common problem with cheap caps. If there is too much ESR the cap can actually hurt your performance. You want a cap with the lowest ESR possible. |

I was thinking hmm... a 2nd order filter for a power supply? eh, what? Translating for us seems to be even harder apparently. High ESR is why a lot of the high capacitance devices like these 100Fd caps and batcaps etc are so useless in car audio. I covered that in several other posts though.. this guy's asked about two dozen questions in the last 3 days. |

Bronze Member Username: PanamanianPanama cityPanama Post Number: 53 Registered: Aug-05 | haha not at all. and yes i meant a capacitor with an external resistor. and no, i 'm asking several question because I will soon buy my stuff and since my budged is limited i dont want to have a bad investment. I could say I am 98% clear now with you guys explanations, and i thank that. in this graphic shows that the current is much more stable with a resistor: ------------------------------------ http://powerzone.com.uy/articulos/electronica/capacitores/capacitores.htm ------------------------------------ |

That'd be a massive waste of power there, and a great car heater as well. I understand not wanting to waste money.. especially since I'm sure things cost considerably more in Panama than they do in the US for audio gear. |
